Genetic Recombination, Gene Linkage, and Applied Genetics

What is genetic recombination?

• The combination of genes produced by crossing over and independent assortment.

• When genes located close to each other on the same chromosome tend to travel together during meiosis.

• A map that shows the sequence of genes on a chromosome.

• The occurrence of one or more extra sets of chromosomes.

What is Hybridization?

• breeding an organism with a known genotype with an unknown genotype and using the offspring to determine the unknown.

• Breeding 2 closely related organisms.

• Breeding organisms to create hybrids.

• A process of selecting desired traits to be passed on to offspring.

What is polyploidy?

• The combination of genes produced by crossing over and independent assortment.

• When genes located close to each other on the same chromosome tend to travel together during meiosis.

• A map that shows the sequence of genes on a chromosome.

• The occurrence of one or more extra sets of chromosomes.

What is a Test Cross?

• breeding an organism with a known genotype with an unknown genotype and using the offspring to determine the unknown.

• Breeding 2 closely related organisms.

• Breeding organisms to create hybrids.

• A process of selecting desired traits to be passed on to offspring.

• is lethal in humans

• increases genetic variation

• separates during crossing over

What is selective breeding?

• breeding an organism with a known genotype with an unknown genotype and using the offspring to determine the unknown.

• Breeding 2 closely related organisms.

• Breeding organisms to create hybrids.

• A process of selecting desired traits to be passed on to offspring.

What is a chromosome map?
